For most horses, at least half of their diet should consist of high-quality grass or hay. Many kinds of grass and legume hay are easily consumed by horses, particularly if the feed is of a good caliber. When buying hay, the two most frequent issues that horse owners run into are locating a stable and reliable source and figuring out whether the hay is of a suitable quality for their horses. Because their digestive systems differ from horses’ and because they can break down fibrous materials more effectively, cattle can use hay that is higher in fibrous content or of inferior quality. Poor quality hay causes horses’ bodies to not be able to digest it properly, which increases the risk of impaction colic. Therefore, confirm that the hay you buy is “horse” hay.
